Orioles have three-year deal with Korea's Yoon

The Orioles have agreed to a three-year, $5.75 million contract with South Korean pitcher Suk-min Yoon pending a physical, a Major League source said Thursday.

The news comes a day after Yoon tweeted a picture of himself in an Orioles cap. His signing is the first big move by Baltimore this offseason.

The Orioles' offseason has included two agreements -- with reliever Grant Balfour and outfielder Tyler Colvin -- that were voided following physicals. The organization intends to make sure everything is squared up with Yoon before it announces the deal.

Baltimore has yet to add a veteran starter, which they need, and while Yoon would help with depth, he's certainly not the kind of innings-eater who fits the bill. Pitching in relief due to an injury last season, Yoon could be a starter or reliever for the O's. He went 3-6 with a 4.00 ERA and seven saves last season. His best pro season in South Korea was in 2011, when he went 17-5 with a 2.45 ERA.
